I'm running two machines, one XP Pro machine hardwired to the router, and one XP Home machine connected to the same router wirelessly. Both machines are on the same workgroup in the same subnet and can access the internet. The hardwired box is able to ping itself and the wireless box. The wireless box can ping itself, but not the hardwired box. Both computers have the same file sharing settings. The hardwired box has its Windows Firewall disabled, and the wireless box has the File and Printer Sharing exception enabled in the Windows Firewall settings. Disabling the Windows Firewall on the wireless box has no effect. The wireless box cannot view its own workgroup.

The following message appears when View Workgroup Computers is selected in the Explorer Window, "Workgroup is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The list of servers for this workgroup is not currently available." I've tried editing the registry entries for NetBT\Parameters\nodetype and \dhcpnodetype, but no settings seem to make any difference.

Now this one is weird: I can get an "ipconfig /all" response on the wireless box, but attempting a "net view" with any options will result in the error code, "System error 6118 has occurred."

If anyone has any idea how to access the network from the wireless machine, please let me know. Below are the results from an "ipconfig /all."

a. Using "Start -> Run":
o Type "\\" without quotes in Open DIALOG box of Start->Run and hit Enter key. For example, "\\Tecumseh". Does window open showing shared resources of the wired computer?
o If no luck, try again with "\\"; e.g. "\\192.168.10.101".

b. Using "ping":
o Ping uses the ICMP protocol for both the request and the response, so either disable the Windows Firewall (both wired and wireless computers) or modify settings to allow access to the request and response. Maybe the ICMP "Settings" BUTTON on Advanced tab of Windows Firewall?
o Ping IP address of wireless computer (yourself); e.g. "ping 192.168.10.102"
o Ping IP address of router IP address; e.g. "ping 192.168.10.1"
o Ping IP address of wired computer;e.g. "ping 192.168.10.101"
o Ping of wired computer; e.g. "ping Tecumseh"

c. Check TCP/IP configuration for wired, wireless, and router machines:
o Using TCP/IP protocol; probably should be TCP/IP over NetBIOS to faciliate computer browsing.
o Must all be on same network; apparently "192.168.10.xxx".
o All using Subnet Mask of "255.255.255.0".
o Wired and wireless using Gateway address "192.168.10.1" which should be the LAN IP address of your router.

So... Can you successfully communicate from the wireless computer to the wired computer?

2. Generally home network users complain about two things:
a. Unable to share files and/or printers.
b. Cannot see all of my workgroup computers.

3. Unable to share files and/or printers. Is your wired Windows XP Pro machine setup for "Simple" or "Advanced" file sharing?

Is the guest account active for network connections?
Quote

In User Accounts (available from Control Panel-User Accounts) the Guest account is off by default. However this setting only applies to the ability to log on the local computer using the Guest account. Simple file sharing relies on guest access to shared folders and printers. To verify that the Guest account is active for network access, do the following:

1. Log on to Windows XP with an administrator account.

2. Click Start, click Run, type cmd, and then press ENTER.

3. In the Command Prompt window, type net user guest, and then press ENTER.

4. If the account is active, a line appears in the output of the command that states Account active Yes.

5. If the account is not active, type net user guest /active:yes and then press ENTER.

6. Type exit and press ENTER to close the Command Prompt window.
